To all whom, t may concern.'

Be it known that l, Fnsosnro Benn, e citizen oi' the United Stetes, endresident of Een York, inthe .county of Kings and State of Een: York,lieve invented certain new and nseni improvements in Sockets for Lsmps,5to., ci which the following is o specicetion.

ll-'iy invention relates perticulerly to improveniente in Ineens forfastening the inisolating iinine in the csp end ineens for securing orlocliing the oep end body of the slieil together. Sockets of thisclierscter ere used perticulerly for inclosing incondescent electriclomp switch besos end else niiet ere i commonly termed rendent switches.in constructions of tliis c erscter in order to cornyly with theunderwriters requirements it 1s necessary to provide en insulatinglining in the csp in such e inenner es to prevent time circuit vvirinefrom coming eccidentslly in contect with tile oep. is these sockets erecustomerily mede in two ports detechebly secured together it is alsonecessary to festen the csp lining in Piece so thet it will not fell outin ordmsry hendling.

@ne object is to provide s sim le und inexpensive Ineens o securing thelining of tlie cop in piece. Sometimes these cs. 1ininggs ere mede ofvery denible motorie such es thin peper which 1t is 'difiicult to holdsecurely in place und the thin s er is likely to be torn in handling. Atiiicr end rigid lining is preferable es it sli'ords e more pericctmeans of insulation, for instance, porcelsin or heevy liber.

The special object of my invention is to eiord Ineens of securing such eheevy lining in piece preferably so that it can be rcedily inserted orremoved when neccssery.

Another object is to provide ineens for securing the csp sndbody of theshell to- @other to prevent relative rotation or reletive lon xeitudinelseparation except when it is desire to lseperete them.

'lhe invention contemplates providing the lining oi the csp witii'tvvoormore clips more or less yieldin Vin nature endedopted to iit intocorrespon ing holes or recesses in the oep. These clips moy be formed inverione vveys end the csp lining, tlie invention are illustreted intheeccomsecnred 1n verious vvsys toy some oz the veriousiorms of penyingsingle sheet o drawings. To secure the two erts oi the slrieli togetheres sleeve indicate the csp` is provided 'with tivo or more interiorlyorojecting shoulders end tiic body is provided with correspondingnotches for receiving the shoulders in tlie csp to pre vent relativerotetion. The ce? is :riso provided with en interiorly directed Songe etits lower edge to receive the u per edge ot' the body., The body isprovi( ed with out Werdly end downwardly projecting eetciies adopted toonstage the interior doings 0:5 t Ac csp. "ilie body 1s slotted st onepoint end one of tlie catches is located adjacent tliis slot Where thebody is erticnlsrly resilient. The other cetclies on tiie body ereerrenged op osito this cet/li so es to render tire ettec ent onddetscliment of the ports more convenient.

The external diameter of theody l corresponds to tlm interior diameter ofthe iienge 6 :ind tlic bodyis provided with s number ci catches such es 7, 8 end 9 adopted tointerlock with the upper surface oi the lsnge 6 for preventinglongitudinal separation of the parts.

the catches such es 8 end 9 ere loceted opposite thereto so that theports cen be more readily cssembledor seperated when desired.

The csp is provided' `with one or more shoulders'sucn ce 11 formed forinstence, by indentingg c. portion of the es?. The up er edge of thebody of the shel is rov1 ed with a number 'of notches such es 1 tocorrespond with the number of shoulders 11 in the oep, so that when theports are interloclsed the shoulder and notch construction 'will preventrelative rotetion of the ports. in the form shown there ere fourshoulders in the azi end four notches in the body the opper en ci theslot 10 forming one or the notches. 'Jhis disposition et the shouldersend notches is perticulcrly useful in preserving 'the ports in theirropes reletive olinement end preventing tl e cody ot the from beingtilted in the cop. llt will he obvious, however, that .eieeser orlgggreeter nnrnher ci shoulders ond notches 'for prerThe end 18 of theclip is bent outward eround the edge of the lining srticulurl es shownin Fig. 5. The cop 1s provide with e. number of openings or recessessuch es 19 adopted to receive the ends 18 of the clips. ln the formshown in Figs. 1 ond 2 these openings 19 nre formed just shove theshoulders 11. The clips formed in this Way ere more or less resilient oryielding so that they can bc readily sprung into place in asf tremblingthe lining 1n the cop. Similarly the ends o the clips may be pried outof the recesses in the csp if it is necessary to remove the linin fromthe cop.

ln 'the form s own in Fig. 6 the cop is provided with sx1-interiorlgroove 20 eti'ording e recess for receiving the ends ot the clips 18 sothat the lining 'con be inserted in enyposition AWithout its beingnecessory to loont/e the lende ofthe cli s in smell recesses es intheform shown in ig. 1.
